Abstract
A video signal processing apparatus, comprises: an image pickup unit, having a focus lens; an evaluation value calculator unit, specifying a region, in which brightness higher than a predetermined value lies, from within a region to be a target, for which a focal point estimation value is calculated to be used for moving the focus lens to a focal point, and to calculate the focal point estimation value by excluding the region, in which the brightness higher than the predetermined value lies, from a focal point estimation value calculation target; and a system controller unit, to be focused upon basis of the focal point estimation value calculated by the evaluation value calculator unit, wherein the system controller unit controls the focus lens to move to a position, which is determined in advance.
